About Us
Guillaume Counseling is an outpatient behavioral health provider serving individuals, couples, and families in Oregon and California. We serve both Medicaid and commercial insurance members, including Oregon Health Plan (OHP) and Medi-Cal members, and also welcome clients who choose to pay privately.
We are incorporated in Oregon as Guillaume Counseling Services, P.C., in California as Guillaume Marriage and Family Counseling of California, P.C., and in Texas as Guillaume Marriage and Family Counseling of Texas, P.C. We are not currently providing services in Texas at this time.
We provide mental health and relationship counseling through in-person, telehealth, and hybrid services. Our approach is individualized, culturally responsive, and trauma-informed, recognizing that mental health is influenced by relationships, family, culture, community, and life experiences.
Mental Health & Relationship Counseling
We provide outpatient mental health and relationship counseling for individuals, couples, and families, with particular expertise in maternal and paternal mental health and the emotional and relational needs that may arise throughout pregnancy, postpartum, parenthood, and family development.
Culturally Responsive Care
We welcome individuals and families of all backgrounds, cultures, identities, and belief systems, with a particular commitment to serving interracial, intercultural, and interfaith individuals, couples, and families. Our services are primarily secular, with faith, spirituality, and personal values incorporated into therapy when requested by the client.
Mission
We are an avenue of tangible hope, healing, and support by working directly with individuals, couples, and families to foster love, respect, health, and safety. Through mental health and relationship counseling, we integrate faith, science, and wisdom to serve diverse communities through culturally specific, trauma-informed care.
Vision
Impacting the world through tangible hope, healing, and support where individuals and families can grow in a safe, secure, healthy, and respectful environment.
